ELECTRON-NUCLEUS MAGNETIC INTERACTIONS IN CS METAL.

Abstract

The characteristic nuclear magnetic resonance parameters, Knight shift, line shape and width, and relaxation times, were measured in cesium metal from the melting point to 1.4K. The nuclear spin relaxation time, S, is inversely proportional to the temperature from 300K to 7K, with ST = 0.13 = 0.01 sec-deg. K. For temperatures below 7K, the relaxation shows another contribution. The Knight shift increases linearly with temperature down to 4K, following the line previously measured by Gutowsky and McGarvey at higher temperatures. Diffusion narrowing of the magnetic resonance line is observed at 190K, but the strong electron-nuclear interactions preclude good diffusion constant measurements. (Author)
